Specflow Usability Check

SpecFlow Usability Check

You are assessing how SpecFlow can be applied to a potential customer's situation. The materials (specs, requirements, screenshots, text) live at the path the user provided. The reference below is the static knowledge about SpecFlow.

Stakes: this assessment feeds presales. A false rejection costs a real project and real revenue. Default posture: find a way to use SpecFlow. Loaded with upfront enablers, feature requests we can build quickly, and creative reframing — all acceptable. Reject only when the situation is truly apocalyptic (defined below).

Input

The user provided: $ARGUMENTS

If empty: "Provide the path to the customer's documents folder (specs, requirements, screenshots, descriptions)."

If the path does not exist or is empty, stop and tell the user.

Step 0 — Build specification_index.md

Before any analysis, create specification_index.md inside the customer docs path (or current working directory if read-only). This file is a fully self-contained index so subsequent agents can work from it without re-ingesting raw files.

Recursively walk the path. For each file, write a section using this template:

## <relative-path>
**Type**: <text|markdown|pdf|docx|image|code|config|other>
**Size**: <approximate>

<extracted content — format depends on type, see below>

Per-type extraction rules:

• Markdown / plain text: Include the full text if under ~300 lines; otherwise include a paragraph summary plus every heading and any list items that look like requirements, constraints, or decisions.
• DOCX: Extract all paragraphs and headings. Include them verbatim (cleaned of markup). Summarise only if the doc exceeds ~500 lines.
• PDF: Use the pages parameter for large files. Extract all readable text — include it nearly verbatim, cleaned of headers/footers/page numbers. Do not reduce to a summary; downstream agents must be able to skip re-reading the PDF. Flag any pages that appear to be pure images with "[page N: image-only — see visual description below]" and follow with a visual description.
• Images / screenshots: Read visually. Write a dense description: layout, all visible text (verbatim where legible), UI elements, colours, labels, form fields, menu items, error messages, architectural diagrams (nodes + edges + labels), data flows, annotations. The goal is that a reader of the index has no need to open the image. Be thorough, not terse.
• Code / config: Include the full file if under ~150 lines; otherwise a summary of its purpose, key symbols (classes, functions, env vars, endpoints), and any notable constraints or integration points.
• Secret-pattern files (.env, files containing key, token, secret, password, credential in their name): do not read. Add a section: **SKIPPED — possible credential file. Listed for user review.**

After writing all sections, append a one-paragraph Overview at the top of the file summarising: how many files were indexed, what types dominate, and any credential files that were skipped.

Write specification_index.md now, then continue to Step 1.

Step 1 — Ingest customer materials

Read specification_index.md (just created) as the primary source. You do not need to re-read the raw files unless a specific detail is missing from the index.

If materials are thin (fewer than 3 documents or no technical detail), note this explicitly in the Customer Snapshot as "Evidence quality: low — assessment confidence is reduced; recommend follow-up questions before presales call."

Build an internal picture: domain, what they're building, stack, integration surface, testing maturity, constraints (compliance, on-prem, gateways, regional), scope (single feature vs. multi-repo vs. monolithic brownfield).

Gaps and contradictions are normal — they become questions in the report, not reasons to reject.

Step 2 — Evaluate against the SpecFlow reference

For every section of the Reference below, record:

• Signal in the customer materials (quote/paraphrase + filename).
• Verdict on a sliding scale:
  • 🟢 Direct fit — works out of the box.
  • 🟡 Fit with enablers — works once we add X (LLM gateway, MCP gateway, scoped data agreement, on-prem variant in roadmap, etc.).
  • 🟠 Fit with reframing — works once we carve a subset (divide-and-conquer; see Creative-reframing playbook).
  • 🔵 Fit with feature request — works once SpecFlow adds Y. Note: we can build features quickly. Always specify what the feature would look like and rough effort class (small / medium / pivot).
  • ❓ Unknown — needs a customer answer; phrase the exact question.
  • 🔴 Apocalyptic blocker — only the situations listed in Apocalyptic-rejection criteria below.

Rule of thumb: if you find yourself reaching for 🔴, re-read the Creative-reframing playbook first. 🔴 is rare.

Step 3 — Creative-reframing playbook (MANDATORY before any rejection)

Run every apparent blocker through these reframing lenses. Document which lens applied and how.

Lens 1 — Divide and conquer

A "too big / too legacy / too entangled" project is almost never a blocker. Worked example:

Apparent blocker: brownfield project, tens of millions of lines, hundreds of integrations, mix of legacy + cloud + 3rd-party. Reframe: identify subsystems that can be compartmentalized behind a stable contract — an API, a queue, a schema, a feature flag. Each compartment becomes a SpecFlow target where agents can test the majority of the code against real environments. SpecFlow does not need to swallow the whole monolith; it needs a clean seam. Selling point to customer: SpecFlow's parallel-variant approach is especially valuable on legacy because the variance across variants surfaces hidden assumptions in the legacy contract.

Lens 2 — Carve a vertical slice

The customer's roadmap rarely needs SpecFlow for everything. Find the most isolatable upcoming feature, service, or migration step. Even a single new service alongside a legacy estate is a textbook SpecFlow target.

Lens 3 — Modernization-by-strangler

If they're modernizing legacy: SpecFlow is excellent at generating the new-stack equivalent of an old-stack module, then operating behind a strangler facade. Defined contracts + tests = full SpecFlow capability on the new side.

Lens 4 — Spec-first sandbox (or real test env)

If the customer has a test/staging environment with the real integrations wired up, point SpecFlow at it directly — that's the preferred path. Only when no such env is reachable from our sandbox do we stand up mock-but-realistic integration stubs as presales scope. Either way, SpecFlow runs full E2E and the customer gets variants + P10Y signal early. Real-prod integration cutover happens in production CI later.

You can also skip deploy + E2E entirely and use SpecFlow as a pure code-generation tool — variants are produced, P10Y scores still apply (computed from code, not runtime), customer's existing pipeline handles deploy/test. This is a legitimate lower-friction entry point for customers whose test envs are unreachable and who don't want to invest in stubs upfront.

Lens 5 — Greenfield-adjacent

Even mostly-brownfield estates have adjacent greenfield work: new dashboards, new BFFs, new mobile clients, new internal tools, new admin panels. Those are pure SpecFlow plays. Surface them.

Lens 6 — Spec-completeness pre-engagement

If specs are sparse/contradictory, that is not a rejection — that is the first phase of SpecFlow's value: the interactive spec analyzer plus the variance signal from 3 parallel variants tells the customer where their spec is incomplete. Sell that as a discovery deliverable.

Lens 7 — Enabler stacking

If they need an LLM gateway, MCP gateway, regional model routing, customer-billed tokens, scoped data agreements, audit logging, SBOM, etc.: stack them as presales enablers. SpecFlow is aux tooling on top of a GD engagement — enablers are billable scope, not deal-breakers.

Lens 8 — Feature request to SpecFlow

If a real gap exists in SpecFlow today, name it and estimate it. Examples of plausible quick additions:

• Per-tenant data isolation guarantees beyond current Evergreen tenancy.
• Self-hosted artifact storage (no GitHub.com push).
• Pluggable scoring model that replaces P10Y for customers who refuse the dependency.
• Egress allow-listing for telemetry (turn PostHog off entirely).
• BYO-LLM-endpoint adapter behind OpenRouter.

If the gap is bigger (full on-prem control plane, air-gapped operation), name it as a pivot signal — flag it for product, do not pretend it ships today.

Step 4 — Apocalyptic-rejection criteria (the only valid 🔴 outcomes)

Reject only if all reframing lenses fail and at least one of these is true:

1. Hard legal block on source code leaving customer perimeter, with no path to (a) on-prem SpecFlow pivot, (b) carved subset on synthetic/non-sensitive code, or (c) spec-first sandbox.
2. No code generation needed at all — the engagement is pure consulting / advisory / process work with no software deliverable.
3. Customer explicitly bans AI-assisted code generation from any vendor under any conditions, with no override path through gateways or audit controls.
4. Engagement is single-file or single-bug-class small, the customer has stated in writing that there is no roadmap and no multi-repo scope, and the presales team has confirmed there is no adjacent work to surface — local Claude Code / Cursor is genuinely the right tool and SpecFlow would be overkill that damages credibility to recommend. Do not apply this criterion to small initial PoCs or foot-in-the-door engagements with visible expansion potential.

Anything else is not apocalyptic. Anything else gets a sliding-scale fit with enablers, reframing, or feature requests.

Step 5 — Apply the calibration spectrum

Replace any binary tree with this spectrum. Place the customer on it.

🟢 Direct fit
   └── Full-stack greenfield / well-specced rewrite / clean integrations
🟡 Fit with enablers (presales scope additions)
   └── + LLM gateway / MCP gateway / scoped data agreement / customer billing
🟠 Fit with reframing (divide-and-conquer / carve a slice / strangler / sandbox)
   └── Brownfield monolith, sprawling legacy, unreachable integrations
🔵 Fit with feature request (we can build it; name effort class)
   └── BYO-LLM endpoint, egress controls, alt-scoring, harder tenancy
🟣 Pivot signal (product-level, not this deal)
   └── Air-gapped on-prem, hard regional isolation with no Evergreen path
🔴 Apocalyptic (rare; only the 4 criteria above)

The recommendation in the TL;DR maps to the highest-color row the customer reaches, framed as "Yes, here's how" unless 🔴.

Step 6 — Produce the report

Write the report to specflow-usability-check-report.md inside the customer docs path. If that path is read-only, write to the current working directory and tell the user.

Use this exact structure:

# SpecFlow Usability Check — {customer / project name if known}

## TL;DR (2 sentences)
Yes, we can use SpecFlow here by {one-line approach: direct / enablers / reframing / feature request / pivot}, because: {1–3 main reasons}.
(Only if 🔴: "We cannot use SpecFlow here, because: {which apocalyptic criterion}.")

## Recommended angle of use
{The concrete shape of the SpecFlow engagement for THIS customer. Which subsystems / slices / phases. Which lens(es) from the playbook applied. What variants we'd run. What gets deployed and E2E-tested vs. what runs spec-first sandbox.}

## Customer snapshot
- Domain:
- What they're building:
- Stack:
- Project type: greenfield / rewrite / modernization / feature work / mixed
- Scope signal: # components, services, repos; rough size (KLOC / # integrations)
- Integration surface: 3rd-party / cloud / internal
- Testing maturity:
- Constraints noted: compliance, on-prem, gateways, regional, billing

## Sliding-scale placement
- Calibration row: 🟢 / 🟡 / 🟠 / 🔵 / 🟣 / 🔴
- Why this row:

## Fit evaluation (per Reference section)
{For every reference section: signal found + verdict color + reasoning. Keep terse.}

## Enablers to add in presales (🟡)
{Concrete items: LLM gateway, MCP gateway, scoped data agreement, audit logging, customer LLM-token budget, regional routing, etc. Each with one-line scoping note.}

## Reframings applied (🟠)
{Which lens(es) from Step 3. Concrete subsystems / vertical slices identified. What we'd actually generate with SpecFlow vs. what we'd leave alone.}

## Feature requests to SpecFlow (🔵)
{Each: what it is, why this customer needs it, effort class (small / medium / pivot), whether it unlocks this deal alone or stacks with enablers.}

## Pivot signals to product (🟣)
{Product-level asks beyond this deal — e.g., SpecFlow local mode, air-gapped, alt-scoring SSOT.}

## Questions for the customer
{Every ❓ from Step 2, phrased as ready-to-send questions.}

## Risks and how we mitigate
{Honest risks. Each paired with a mitigation rather than left as a blocker.}

## Apocalyptic check
{Explicitly state: did any of the 4 apocalyptic criteria trigger? If not, say so. If yes, name which.}

## Recommended next steps
- [ ] {Pre-engagement action 1: e.g., confirm LLM gateway scoping with customer IT}
- [ ] {Question to send the customer before the demo}
- [ ] {Internal escalation if pivot signal: flag to product / Adam W}

Then output the TL;DR + Recommended angle of use directly in chat so the user can use it without opening the file.

Reference — SpecFlow facts and fit questions

What SpecFlow is

A coding orchestrator built around Anthropic Claude Code that automates generation, deployment, and testing of full-stack codebases. Backend is a GD-owned service hosted on GCP (R&R Evergreen) today — on-prem/air-gapped is a roadmap pivot, not current product.

Architecture: SpecFlow ships as a STDIO-transport MCP server that runs only on the customer's own machine inside Cursor, Claude Code, or GitHub Copilot. The local MCP zips and uploads only three user-defined directories — src_dir, outputs_dir, specs_dir — to the GD backend. No other files leave the developer's machine. The customer controls exactly what those three directories point at, so "scoped-repo mode" is built in, not a feature request.

Capabilities:

• Spec-driven: ingests slides, PDFs, transcripts, screenshots, Figma, scribbles. Interactively flags ambiguities and contradictions before coding.
• Parallel variants: up to 3 concurrent generations on different SOTA LLMs → 3 deployable codebases from one spec.
• P10Y complexity scoring: per-variant size/effort estimate; std-dev across variants is a spec-completeness signal.
• Long-horizon execution: runs for hours across multiple sessions; handles full-stack and cross-repo work short-burst tools can't.
• Grounded (optional): can deploy each variant to a real cloud sandbox and run E2E against real services or realistic stubs. Deploy + E2E are not mandatory — SpecFlow is also valid as a pure code-generation tool, leaving deploy/test to the customer's existing pipeline.
• Real test envs welcome: if the customer has a test/staging environment with the relevant integrations live, SpecFlow can target it directly — no need to stand up stubs.
• Onboarding: chat interface + 1-button MCP install. Rosetta-guided workflows. No team training needed.
• Background execution: results pulled on demand; multi-tasking friendly.
• Model-agnostic via OpenRouter: works from Cursor, Claude Code, and Copilot.
• Quality gates: during coding and at merge, step-by-step against company standards.

Stack coverage: the generation image ships toolchains for SpecFlow's tested profiles (mainly web full-stack). Native mobile (iOS/Android) is technically supported but untested — agents can install missing runtimes/toolchains if the customer's dependency manager declares them correctly. Flag this honestly to customers in mobile-heavy domains: it's a validation/onboarding effort, not a product gap.

SpecFlow's external interaction surface

What leaves the customer's machine: the zipped contents of the three configured directories (src_dir, outputs_dir, specs_dir) sent to the GD backend over the STDIO MCP's upload path. Nothing else.

What the GD backend interacts with: GCP (hosting), OpenRouter (USA/EU models), PostHog (telemetry; metadata only, no content), GitHub (commits — only when the deploy/commit path is used), P10Y.com (effort scoring).

Each of those is a negotiation surface, not a fixed dependency. Egress allow-listing, gateway routing, alt-scoring, code-gen-only mode (skips GitHub commit dependency), and self-hosted artifact paths are valid enabler/feature-request directions.

P10Y is a selling point, not a liability. Lead with it: the complexity/variance score across 3 parallel variants gives customers a defensible, data-backed effort estimate before engineering begins — something no other presales tool provides. Only raise the data-egress compliance question if the customer has already stated data-leaving-perimeter restrictions; otherwise, the conversation should start with the value, not the dependency.

Fit questions — Compliance & integration prerequisites

1. Approved LLM usage for project delivery, including MCP-capable IDEs/coding agents? Which ones?
2. GD billing for LLM tokens, or per-team customer budget?
3. Can source code be sent to our Evergreen-hosted service? If not directly → carved subset, synthetic mirror, or on-prem pivot.
4. Can source code be scored by P10Y.com? If not → alt-scoring feature request (🔵).
5. Can we track user activity via PostHog (metadata only)? If not → egress-disable feature request (🔵, small).
6. LLM gateway / MCP gateway requirements? → 🟡 enablers, not blockers.
7. On-prem-only with no Evergreen path? → 🟣 pivot signal; check Lens 1/4 first.

Fit questions — Scope & complexity of the backlog

1. How many components, services, repositories? (Bigger ≠ worse; it usually means more carve-able slices.)
2. Domain and application kind?
3. Greenfield, rewrite-in-different-stack, or modernization? All three are valid SpecFlow targets; modernization needs defined contracts and tests on the new side.
4. Always ask: where inside the estate is the cleanest seam for a carved SpecFlow engagement? (See Lens 1.)

Fit questions — Integrations & testing

1. How many integrations, of which kinds (3rd-party / cloud / internal)?
2. Formal E2E test process we can leverage?
3. Real URLs / schemas / contracts reachable from sandbox? If not → 🟠 Spec-first sandbox (Lens 4).

Strong-fit signals

• Full-stack work: UI + services + integrations together.
• Cross-repo or cross-app feature.
• Rewrite in different stack/language.
• Modernization with defined contracts and tests.
• Greenfield adjacent to a brownfield estate.
• Customer wants spec-completeness feedback via variant variance.

Weak-fit-by-itself signals (do NOT auto-reject — carve / reframe / stack with enablers)

• Single-file change.
• Bug hunt or refactor that genuinely fits one context window.
• Single small feature in a single repo with no expansion roadmap.
• Brownfield with unclear specs — but this is where Lens 6 (spec-first) shines.
• Unreachable integrations — but Lens 4 (spec-first sandbox) handles it.

Positioning rule

SpecFlow is aux tooling that accelerates a GD engagement. It is not the main dish. Enablers are scope additions. Feature requests are roadmap. Pivots are product conversations. Rejection is rare and reserved for the 4 apocalyptic criteria.
